[Help] Extremely Choppy Graphics on OSX Yosemite

Recommended Posts

I have a Radeon 7970 card and I just installed yosemite, I got most of my drivers in working order but my graphics card doesn't seem to be really doing much. Transition animations are extremely slow and cause the mouse to flicker, and when I try and run a browser other than Safari it's impossible to use due to nearly constant flickering.

 

My boot flags are as follows : -v npci=0x3000 PCIRootUID=1 GraphicsEnabler=No

Boot with AtiConfig=Tahiti

 

Do you have a Gigabyte mobo? If not, do not use the PCIRootUID=1 flag and see if it works that way.
